Tov all @07mm t may concern.'

Be it known that I, CHARLES A. Linnnnnc, a citizen or the United States, residing at Sturgis, county of St. Joseph, State o of Michigan, have invented certain new and useful Improvements in VVheel-Locks, of which the following is a specification.

rIlhis invention relates to improvements in wheel locks for ohildrens carriages. The main objects of this invention are t vnovide an improved wheel lock which is very secure, which may be easily engaged and disengaged, is inconspicuous and not likely to get out of repair.

AFurther objects, and objects relating to structural details, will Vdenitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the 'following speciiication. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part oi this specification, in which:

Figure I is a detail rear view of a structure embodying the features of my invention, only such parts of a chilcs carriagg being' shown as seem desirable to illustrate an embodiment oi my improvements.

Fig. II is a detail plan view of the parts shown in Fig. I.

Fig. III is a detail vertical section on a line corresponding to line 3 3 of Fig. II, showing details of the actuating lever.

Fig. IV is a detail horizontal section on a line corresponding to line 1 -fl of Fig. I and-Fim III.

Fig. V is a detail section on a line corre-- spending to line 5 5V o Fig. I structural details of the hub.

Fig. VI is a plan view of a blank from which the actuating lever is formed.

Fig. VII is a detail plan view showing a modified form or adaptation of my invention.

In the drawing similar reference characters reifer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the end oi: the section lines.

Referring to the drawing, 1 represents the axle, 2 a wheel and 3 the running gear frame oi a childs carriage. I do not deshowing scribe these parts in all details as such details form no part of my present invention.

The hub 4 or' the wheel 2 is provided with an annular series oi longitudinal bores 5, and with an end plate 6 having holes therein registering to these bores. The end plate is secured by means of the screws S. The locking rod 9 is mounted on the axle to engage these holes, and when so engaged, locks the wheel against rotation. In the embodiment illustrated the rod is supported by the axle clip 10 having lugs 11 projecting therefrom and through which the rod reciprocates. A coil spring 12 is arranged on the rod between these lugs with one end of the spring engaging one lug and the other a thrust collar 13 on the rod, so that the rod is normally urged toward the hub.

The inner end of the rod engages the hole la and the actuating lever 15 which is pivoted at 16 upon the rear side of the axle. The hole 14 is disposed relative to the lever pivot 16, so that by swinging the lever, theI rod is projected or retracted to engage or disengage the hub. The lever is provided with an arm 18 having a stop portion 19 on its upper edge adapted to engage the top of the axle, as illustrated, to limit the swing of the lever. The lever has an inturned portion Q0, and the arm, being resilient, engages the axle so that the lever is retained in its rod retracting position as shown in Fig. III.

The locking means may be conveniently engaged or disengaged by the foot of the operator, the lever being positioned on the rear axle so that it is accessible. The portion 17, being turned rearwardly, may be easily engaged, a downwad movement ot the lever releasing the lock, and an upward movement thereof locking the same.

In the embodiment shown in Fig. III, the locking rod 9 is supported by clip 21 having a single arm 22 through which the rod reciprocates. The rod is connected to the lever same as in the structure described. The spring 23 in this embodiment is connected to the rod at is and to the frame at 25. This embodiment has the advantage of being somewhat simpler in structure. Its operation is, however, the same as that shown in the other iigures.

My improved lock is very simple and economical in structure. It is economically applied to the carriage or embodied ther in, and strong and durable.

y I have not attempted to illustrate certain other modifications and adaptations which might be desirable for 'different axle and ruiming gear structures, as I believe the disclosure made Will enable those skilled in the art to which my invention relates, to einbodyor adapt the same as may be desired.

IIavi'ng thus described my invention, what I claim asnew and desire to secure by Letters Patent is: v

:1. In awlieellocking device, :the 'combination With an ifa'xle, of a'wlieel mounted thereon comprising la'hub provided 'with an end platefat itsfinner end with an annular series off ho'le'sfy therein, La "locking rod, a ysupporting clip mounted lon said axle adjacent said Wheel and having 'a pair of spaced lugs through Which said locking rod reciprocates to-engagewith said hub holes, a spring alr- "rangedon said vrod between said lugs, jsaid ro'dbeing'provided With a thrust collarV with VWhichone end osaid 'spring engages, anda lever `Withwhi'ch vsaid rod is'pivotally engagged,lpivotally-inounted on said axle, said lever being provided'withv a lock-ing arm engagingfthe laxle When the leveris in position toiretract the locking rod.

2.
